It has before been proposed to use anatural water-bearing stratum as afilter for a supply of 'surface Water to Wells communicating with said Water-bearing stratum; but

such a' supply'of surface Water necessarily' causes foulingof thefiltering `medium, and the-'difficnlty-of effecting a proper cleaningoftlhelatt-eif has heretofore `proven to be' an insiifper'abl'e-obj ection'tofth'e adoption of this metliodjas a means of Water-supply.

Incarryingout my invention I- provideV Qnefor'niore sedimentation basins or reser-H voirs, iii-Which a large percentage of the foreign matterI held in suspensioninv the water can be 'precipitatecflpriorl to conveying said water to 4the stratum or strata intended to 'serve` as a'filtering medium therefor, endl' efiectfthecleaning of such'iiltering medium l when necessary -by the eniploynient of a fluid p under'pressure,.'and preferably b vtheuse of air, in the manner hereinafterset forth. f f lnthe drawings, lrepresents a river or I ASpecii-cationofIiejaterds Patientez' v g ippiicmnn ned June 1.1906. f saisine sientes? as the nios'tlapprb valved;"are-employedlfor ca v n latter communicating at" their oy These objects l I attain in"` k15 and the pumVA may be modified" position:whichflocal conditions v priatef'tlievr be rie dl Y. to tliein vrthrough suitashowninthe 'diavvirigs,V shortp es direct-ly from tliestreainjr 3 'andi-4', icr'deach of' these reservoirs A,ijs 1 communication with each of Flihesfer, to a longitudinalfrnain 12j sourceiof supply 4for a seri with the natural Water-bearings which isito serve as 'the-"filtering each of the branches ybetween'th and the Wells` 12S-being v'alved connnunicatioiibetween L one or In'or'eof' tliejvvells niayfbe'estabhsh l or'c't off ait-will.
